SPRINKLER.

which the following is a specification.

This invention relates to certain new and useful improvements in anozzle or sprinkler to be used in connection with a water supplying hosefor causing the water expelled therefrom 'inafter more fully to bedischarged in the form of a solid or continuous stream or a shower orspray, as may be desired, and it consists in certain peculiarities ofthe construction, novel arrangement and operation of the various partsthereof as will be hereset forthand specifically claimed. p w

The principal object of the invention, is to provide a device of theabove mentioned general character, which shall be simple and inexpensivein construction, strong, durable and efficient in operation, and so madethat it can be used for throwing a solid or continuous stream of waterin a desired volume, for laying the dust in for other purposes, or fordischarging water in the form of a shower or spray, for wateringdelicate plants or lawns.

Another object of the invention is to so construct the device that itcan be used as a stationary sprinkler or fountain, or in other words,can be located on the ground in a fixed and upright position, to theend, that a. given area of a lawn or garden can be sprayed for a desiredlength of time or until it becomes thoroughly saturated or moistened.Still another object is to provide means for discharging spray in theform of concentric circles. A still further object is to furnish meansfor regulating the volume of water discharged through the sprinkler.Other objects and advantages of the invention will be disclosed in thefollowing description and explanation.

In the accompanying drawing which serves to illustrate an embodiment ofthe invention-- Figure 1 is a central longitudinal sectional.

33 of Fig. 1 looking in the direction of the arrows, show ng theadjustable member of the body portion of the-device detached, and

Fig. 4: is a fragmental sectional view of a portion of the body of thesprinkler showmg a modification in the construction of and the means forpacking the combined regulatmg valve stem and support.

Like numerals of reference refer to cor-v responding parts throughoutthe different views of the drawing.

he'reference numeral 6 designates, as a portion of the sprinkler, whichas will be understood from the drawing is elongated in shape and hasits'upper or front portion cylindrical and partly screw threaded. Thelower'or rear portion of the body 6 is cut away to provide a flat wallor surface which is provided at about its middle portion with a screwthreaded rod 8 which is extended at a right angle to the face of thebody. The upper or outer end of the body 6 is provided centrally thereonwith a reduced portion or neck 9 on which is fitted a thimble or cap 10which is contracted at its upper or front end and provided at said endwith an opening 11 which is by preference outwardly flared as shown.Extending centrally and longitudinally from the rear or lower end of thebody 6 into the same, is a screw threaded opening 12 for the receptionand operation of the screw threaded portion of a valve stem 13 which hasits lower or rear portion pointed so as to pierce the ground and toenable it to act as a support for the sprinkler. The upper portion ofthe valve stem 13 is reduced as at 14 and is without screw threads. Thisreduced portion is extended throughthe reduced portion 15 of the opening12 which reduced opening communicates at its inner end with the opening12 and at its front or upper end with the thimble or cap' 10. The frontor upper end of the reduced portion 14 of the valve stem has detachablymounted thereon a head or valve 17 which, as is shown, is enlarged fromeach of its ends toward its middle portion and is of sufiicient size toclose the opening 11 in the thimble or cap 10 when adjusted by means ofthe valve stem.

Mounted on the lower or rear portion of the circles around the upperfront portion of the member 20.

The body 6 is provided with a palr of longitudinally extended channels22 and 23 the former of which communlcates at lts upper or front endwith the space between the thimbles or caps 10 and and opens at itslower or rear end in the flat face 7 of the body 6 at one side of therod 8 on said body. The channel 23 communicates at 1ts upper end withthe cavity of the thimble or cap 10 and opens at its lower or rear endin the face 7 of the body on the opposlte slde of the rod 8 from theopening of the channel 22 as 18 clearly shown in Fi 2 of the drawing.The face 7 of the b0 y is provided around each of the openings 22 and 23therein with an annular boss 2 1 which are for the purpose of engagingsuitable open ngs in a gasket 25 of leather or other sultable material,so as to prevent said gasket turning. This gasket is fitted around therod 8 and 1s interposed between the fiat surface 7 of the body portion 6and the flat surface 26 of the adjustable member of the body, whichmember is designated as a whole by the reference numeral 27 and isprovided with a channeled extension 28, which extension is by preferenceinternally screw threaded at its rear or lower portion to engage. screwthreads on a hose or coupling 29 which has communication with a supplyof water not shown. The channel 30 of the extension 28 extends or opensthrough the fiat face of the adjustable member 27 in the form of asegmental opening or slot 31, see Fig. 3 of the drawing, so that thedesired end of the slot or opening 31 can be placed in communicationwith either of the openings 22 or 23 in the body of the sprinkler. Asshown in Figs. 1 and 3 of the drawing, the adjustable member 27 isprovided with a central opening 32 for the reception of the rod 8 onwhich it is rotatably mounted and can be fixed in the desired positionby means of a thumb nut 33 mounted on the outer portion of said screwthreaded rod.

As shown in Fig. 1 of the drawing, the opening 12 in the body 6 isprovided with an annular enlargement 34 for the reception of packing 35Which can be inserted through an opening 36 extended from the enlargedopening 34 through thewall of the body 6 at a suitable point above thelower or rear end of said body. Located in the opening 36 is a set screw37 which impinges at its inner end against the packing 35 and is usedfor firmly holding the valve stem 13 in its adjusted position.

In Fig. 4 of the drawing, I have shown a modification in theconstruction of the valv stem 13 and in the construction of the opening12 therefor which consists in omittmg the enlargement 34 of said openingand in forming the valve stem with an unthreaded and reduced portion 38which construction will provide a space for packing 35 which can beinserted through the opening 36 in the wall of the body 6 in which theset screw 37 is located. The packing used in either of the constructionsis for the purpose of preventing leakage b back pressure.

From the foregoing and by reference to the drawing, it will be readilyunderstood and clearly seen, that, assuming the parts to be in theposition shown in Fig. 1 of the drawing, the channel 30 in the extension28 of the adjustable member 27 will through its mouth or opening 31communicate with the opening or channel 23 thus causing water to bedischarged through the opening 11 of the thimble or cap 10 in the formof a solid or continuous stream, it being understood that the valve orhead 17 can be adjusted so as to regulate the volume of the waterdischarged. If it is desired to use the device for the purpose ofspraying, all that is necessary is to turn the adjustable member 27 to aposition to bring the mouth 31 of the channel 30 of saidadjustableirnember into communication with the opening or channel 22when it is apparent that water will be discharged through theperforations 21 in the cap or thimble 20 or spraying mem- Having thusfully described my invention what I claim as new and desire to secure byLetters Patent, is

1. Ina sprinkler, the combination with a body having a flat facedcut-away portionand provided with an opening centrally andlongitudinally located in sald 'body, said body also having a pair oflongitudinally disposed openings extending from the front end thereof tosaid flat face, of a cap or thimble mounted on the front end of the bodyand around said central opening and one of the other openings and havingan opemn in its front end, a perforated cap or thim le mounted on thebody around the first named thim'ble, a stem adjustably located In saidcentral opening, a valve or head mounted on the front end of said stem,and an adjustable member rotatably mounted on the fiat faced portion ofthe body and having means to connect it to a hos and a passage way forwater disposed for alternatlve communlcation with said pair of opemngs.
